1932, Serial No. ber '20, 1930 2 Claims. (01. 242-157) The present application is a division of application, Serial Number This invention relates to a novel thread guide holder.

In order to guide freshly spun filaments to suitable take-up means it is necessary that the friction of the filaments and guiding means be maintained constant, and the stretching of the filaments uniform. If such results are not obtained the filaments will possess irregular tensile strength, elongation and irregular dyeing quali res. countered in leading the freshly spun filaments over an oscillating guide to suitable take-up or collecting means has been found to be due to the manner in which the thread guide is secured to the oscillating thread guide holder. A comparatively small amount of play in the connection causes an unevenness in the stretching and the friction between the filaments, thus causing the above mentioned irregularities.

It is, therefore, an object of this inventionto provide means whereby the thread guide may be securely fastened to the thread guide holder.

means which will prevent any shifting oithe thread guide in either a lateral or longitudinal direction with respect to the thread or support.

These and other objects of this invention will become more apparent from a perusal of the following description and a'study of the drawing in which:

Figure 1 is a frontelevation of one embodiment of the invention; Figure 2 is a side elevation of the parts shown in Figure 1, a part of the holder being in section; and

guide holder Figure 3 is a section taken along the line 3-3 of Figure 1.

In the embodiment shown in Figures 1, 2 and 3 the thread guide holder l' is formed with a 563,206, filed September 16, 1931, now U. S. Patent No. 1,959,158, of May Moreover, since the Much of the existing difficulties now en-- 635,125. In Germany Novemdepending portion H. A groove 13 extends along both the depending and horizontal portion of the holder as is clearly shown in Figure 2.

This groove provides a seat for the thread'guide rod which in this instance hasin additionto a}.

thereof, at right angles tothe hook I, a part l4 thread guide rod. V

Bythe above construction it may readily be seen that due to the'fact that the threadguide rod is held in thegroove by a ring I6 it cannot shift laterally with respect to the holder I.

portion I4 is bent at right angles and held in longitudinal shifting is prevented. v

It is to be understood that the terms used indescribing and claiming the invention are used in their descriptive sense and not as terms of place by the ring l any. f

limitation, and it is intended that all equivalents of these terms be included within the scope of the appended claims.

I claim'- 1. In combination, a support comprising a horizontally extending portion and a vertically depending portion having a groove extending the length'thereof, a bent thread guide rod positioned therein, means to detachably secure the thread A further object of this invention isto provide.

the support, a thread guide rod having a hori-' zontally extending member positioned in the groove formed in the corresponding horizontally extending member of the support, a ring for holding the horizontally extending member of the.

position and a secondringfor holding the thread guide rodto'the vertically.

thread guide rod in depending member of the support.
